Description
Product Introduction & Engineering Value
Large Series 90-30 PLC racks frequently reach the current limit of a standard power supply, especially when populated with multiple communication and analog modules. The GE IC693PWR330 addresses this requirement by providing a higher-capacity power source while maintaining compatibility with existing Series 90-30 hardware.
Designed for installation in the leftmost rack position, the module distributes regulated power across the PLC backplane while supplying dedicated outputs for relay circuits and isolated field power. Its wide AC/DC input range also simplifies deployment in facilities using different control power standards.

Field Application & The “Trench” Experience
A packaging plant experienced intermittent PLC resets whenever several high-speed conveyors accelerated simultaneously after maintenance. Initial troubleshooting focused on the CPU, but voltage measurements showed the existing power supply was operating near its maximum +5 VDC capacity because several communication modules had been added over the years.
Replacing the original supply with an IC693PWR330 restored sufficient power margin, eliminated unexpected processor resets, and stabilized the entire control rack without replacing any CPUs or I/O modules.
Typical applications include:
- High-density Series 90-30 PLC racks with numerous analog and communication modules
- Water treatment PLC control panels requiring isolated 24 VDC field power
- Steel mill furnace control cabinets with mixed AC/DC control power

The Veteran’s Tech Trap Guide
⚠️ Don’t Size Only by Total Wattage
Many engineers notice the 30 W rating and assume every output can deliver its maximum simultaneously. That’s incorrect—the combined output of all three supplies cannot exceed 30 W.
⚠️ Always Install in the Leftmost Slot
The IC693PWR330 is designed as the rack power source. Installing it elsewhere will prevent proper backplane power distribution.
PRO TIP:
Before replacing a failed power supply, calculate the existing +5 VDC load. A supply operating continuously near its limit often indicates that the rack has expanded beyond its original design.
⚠️ Inspect Battery and CPU Health
A failing power supply may resemble CPU or memory faults. Check battery condition and backplane voltage before replacing the processor.
Dynamic FAQ
Q1. What PLC systems support the IC693PWR330?
It is designed specifically for GE Fanuc Series 90-30 PLC systems and installs in the rack’s leftmost power supply position.
Q2. Why choose the instead of the standard power supply?
The provides a higher +5 VDC capacity, making it suitable for racks populated with additional CPUs, communication modules, and analog I/O.
Q3. Can the module operate from both AC and DC power?
Yes. It accepts 85–264 VAC or 100–300 VDC input, allowing installation in a wide variety of industrial control panels.
Q4. Is New Surplus inventory unused?
Yes. New Surplus units are genuine unused OEM inventory that has remained in warehouse storage and has not been placed into industrial service.
Q5. Do refurbished units undergo functional testing?
Yes. Refurbished modules are inspected, electrically tested, and output voltages are verified before shipment.
Q6. Is the still manufactured?
No. The Series 90-30 platform has been discontinued by the manufacturer, but New Surplus and refurbished inventory remains available through industrial spare-parts suppliers.
